VEHICLE SN'BBER ANDESHGCK ABSORBER.

I Application filed V.Aug-11st 1 The inventionrelales to Yvehicleisnubbers;nparent. .Arpspring and has among its objects to provide a device of thecharacter specified which shall be of simple construction. fAnotherobject "off the invention is to provide. means for effectively absorbingtheroad shocks of auto-y A further object of the invention lies-in-the provision of' af snubber which iscapable ofv being malnufacltured at a low cost.

' lVith these `and other objectsin -view,=fthe invention residesv` in the novel-featuresoff` `construction land combinations andv arrangescribedr and claimed. l

..1 A horizontallyA extendingiarm=28 isvkeyed at one end 'with the shaft 14: and is pivotally connected rtf-32 to a vertically extending rod 29 preferablyiadjustable in length as at' 30. The. lower vend. of rod 29 is secured to a fastening 31 mounted on the1afxle11. Anut S8 and washer S4 serve to position ,the arm 8. v Inoperation, .whenthe vehicle strikes: an obstruction theaxley 11 ,will be `moved toward the'` kframe 10 forcing :rod 29 .upwardly and causing arm 28 to-rotate thefdrum 15 through the' shaft 14, inV a clockwise :direction as viewedin Figure 2. Movement-of thefdrum in this direction is unaffected by the Awedge shaped braking, element the drum surface f :sliding WithrespeCt tothe. eontacting surface of the brake yelement 20.'iSpring 26 acts through thellink 21to maintain the posie .,tonofthe brake kelement aszshown' in Figure 2. Howeven when the'aXle 11 moves downwardly as viewed in Figure 1, on its I ,rebound-,the `drum 15 vfrictionally' engages the braker element'20V tending to rotate the same. in acoun'ter clockwise direction., :The spring 26 aids the movement ofthe'brake ele- 1], @dy-Wimg the, vehicle Wheels in any. rSu1;..1nen.tv inifthis :direct-ion.;Movement ofthe formed with a Peripheral faceV 16l POD which is mounted a frictionbrake-band V17." The drum housing is formed with a bored projection 18A and air inner face"19 preferably curved eccentrically with respectto the drumcenter as shown in Figure 2Q Between the band 17l and the face 19 a? wedge Vshaped braking element 2O is providedhaving an innerl face curved to contact with the band 17 and any outer face preferably curved tojcorrespond` with the face 19 of housing 13. To one end of thebrake element 2() is'pivoted the link 21.l The other end of thel link is pivoted to an axially movable adjusting rod 22 threaded at'23 to receive a nut 24. [reap 25 forms a closure for `the bored projection i 18, the outer face of'thecap-serving asan abutment for nut'24 as will be presently apbrake element iszpreventedby reason of its wedge sha-pe acting-.along the `facev19 of drum .housing 13. vMovement of the .axle 11 is thus checked. lThepo'sition ofthe brake nut'r 24 in'order to obtain the; desiredy amount off braking for fthe reciprocations of: the vehicle axle. The spring 2Gtends-tomaintain the brake element' inf' its adjusted 'wcounter clockwise position, aiding also toincrease the lfrictional resistance? at the friction yband.

1-7- duringithe braking or snubbing. movement of the axle.

lReferringto Figure 4, 1 have disclosed a shock absorber embodying a' modified form of my invention. In thisconstruction a second wedge shaped:brake-element 20', similar to the element 20, is positioned to act on the drum 15 whenthe` latter isvrotated in a clockwise direction corresponding to an upward movement of theaxlell." Thus, movement of the axle is resisted in eachdirection.

' `lVhile I have 4shownf'only ionevbrake vele- Vment acting on the' drumin any direction it `element 2O may beadjusted by'reason of the Y is `obvious that any number might be employed engaging the periphery of the triction band.
